WebNov 1, 2006 · In austenitic stainless steels, corrosion resistance is provided by a very thin surface film, known as passive film that is an invisible film of oxide, formed by the metal reacting with the ambient environment. Normally these films are free of pores, but their stability may be weakened locally. WebJan 2, 2024 · Intergranular corrosion, also known as intercrystalline corrosion, is a form of corrosion that occurs along grain boundaries in metals. It is primarily caused by the preferential dissolution of one component in a multiphase material, resulting in the localized attack along the grain boundaries. tsm25s4WebIC (Intercrystalline Corrosion) is a form of corrosion that can occur in most alloys at the appropriate conditions.
